VAPOR-STOVE BURNER.

SPECIFICATION forming part of Letters Patent No. 384,511, dated une 12, 15388.

Application filed July 25, 1887. Seria'l )70,245,231 (No model.)

To all whom t may concern.'

Be it known that I, ZEEULON DAvIs, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Stove Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such' as will enable others skilled in the art to which it pertains to make and use it, reference beinghadtotheaccompanyingdrawings,which form part of this specification.

My invention relates to an improvement in vapor-burners.

rlille objects of my invention are to provide a vapor-burner in which a post or standard rises directly from the generating-chamber for the purpose of receiving the cap of the burner, to havea portion of the burner-flame serve as a subsidiary jet without in any manner decreasing the amount of heat from the burner, and to cause an equal distribution of the vapor inside of the burner, so that the gas will burn evenly from all sides alike.

Figure 1 is a side elevation of a vaporburner embodying my invention, partly in section. Fig. 2 is a plan view of the same, the cap of the burner being removed. Fig. 3 isa perspective of a plate which is placed inside ofthe burner to cause an equal distribution of the vapor. Fig. 4i is a vertical section of the burner, taken at right angles to Fig. 1. Fig. 5 is a detached side view of the burner, taken from the opposite side from what is shown in Fig. 1. Fig. 6 is a vertical section shown in perspective of the burner, taken upon the line 38 of Fig. 2.

A represents the stand-pipe, and B the vaporizing-chamber formed in the casting B', which is screwed upon its top. Thisvcasting B is east with a core in a single piece complete, with the opening G, the post D, and vaporeondueting pipes E. The induction-tube Cis made of rcast-iron and fastened to the side of the casting in any suitable manner opposite the opening G. The top I of the chamv ber B is made'concavo-eonvex, as shown, and

also forms the bottom of the chamber H, into which the vapor is projected. By depressing this part I, as shown, the top of the chamber B is contracted, so that the vapor, afterthe burner becomes heated, is held between two highly-heated surfaces, and thus not only is a greater amount of the fuel vaporized, but a more perfect vaporization takes place than would be the case if the part I were not depressed, as is here shown.

Rising from the top of the part I is the post or standard D, which is screw-threaded at its upper end, so as to have the top J of the burner screw upon it, and thus clamp and hold the perforated ring K, through which the vapor burns, rigidly in position upon the top of the vaporizing-chamber B. The top J becomes intensely heated by the dames and transmits a portion of its heat through the post or standard D to the part J, and thus converts the part I into a vaporizing-surface at the same time that it serves to prevent any of the vapor entering the chamber H through the induction-tube C from becoming condensed.

I-n 'the top of the casting in which the chamber B is formed there is a suitable recess, down into which the lower edge of thering K is placed. Around the outer upper edge of this recess is formed a projecting flange, Z, under which a small portion of the dame burning on the outside of theV perforated ring K catches for the purpose of heating the top of the chamber. In order to convert both the concaved portion I of the eastingin which the chamber B is formed and the outer walls of the chamber into vaporizingsurfaces, there areformed small openings L through the top of the re.- tort, and through which openings are projected portions of the flame burning on the outside of the perforated ring K.

To hold that part of the flame which passes through the opening in contact with the outer surface of the chamber B, there are formed around these openings L, upon opposite sides of the chamber, as shown in Fig. 4, suitable inelosing-walls, M, which serve to prevent any escape of heat, and which absorb the heat of the Haines which pass throughl the openings L, and thus heat the chamber B at its top and on its outer side, so as to assist in the vaporization of the fuel. Any heat which does escape from in between the inelosiug-walls M rises directly upward against the cookingutensil over the top of the burner, and hence no part of the flame issuing from the perforated riug K is lost; also, formed through that side of the top of the chamber B which is next to the conducting-pipes E are formed two openings, N, (shown in dotted lines in Fig. 2,) and through which openings N are also projected portions of the flames which issue from the perforated ring K, and these lOO` flames issue just under the web O, which unites the three delivery-tubes E together, and thus serve to keep the tubes E het and to prevent any condensation of the vapor while passing through them. In order to keep the ring K at a suitable distance from the openings L N, small projections or lugs I are formed upon the inner edges of the tlange Z on top of the chamber B, and these lugs I? serve to center the ring in position and to keep it from closing over against any of the openings, so as to prevent a free passage of tlame through them.

To prevent the vapor which is projected through the induction-tube C from being forced unevenly through the farther side ofthe burner, a plate, Q, which is cut away upon one side, is passed down over the top of the post D, and this plate forms the top of the chamber H. The vapor, as it passes through the opening` G, strikes against the post B and passes around its side and rises up against the under side of the solid portion ot' the plate Q. From this solid portion of the plate Q the vapor passes back toward the side of the chamber H at which it entered, and then rises through the opening R and spreads evenly through the burner. As the gas rises evenly into the space or chamber inside ot the perforated ring K, it burns from all sides ot' the ring K with equal force. \Vere no plate Q used the gas would be projected through the ring K on the opposite side of the induction-tube C, and thus burn with a blowing sound from this side, while but very little tiame would issue from any ofthe other sides. Rising from the top of this plate Q is a collar, T, which is provided with a groove, U, upon one side, which collar and groove tit down over the post D, as shown in Fig. 2, the post being provided with a rib upon one side for the purpose of preventing the plate from turning around, and thus getting out of position.

Through the underside ofthe pipe E, through which the vapor is conducted to one of the needlevalves, is made a screw-threaded opening, V, and this opening is kept closed by a suitable plug when only three burners are desired.

The precise location ofthe opening V is im material, for it maybe made under any one of the pipes, just as may be preferred.

\Vhen it is desired to add an additional burner, either for the oven or for any other part ot' the stove, a detachable conductingpipe, X, is screwed into the opening after the plug has been removed, and which pipe X carries a necdle-valve, Y, of its own. This detachable pipe K may be left in position upon the burner; but in' order t-o prevent any mistake in operating the wrong Valve when no fourth burner is needed, this pipe K will be removed and the opening again closed by a plue. 2y the use ot` a removable conducting-pipe, X, any stove having a central generating-burner can have an additional burner added to it whenever so desired.

I'Ieretofore when a vapor-stove having a central generator was made but for three burners there was no way of increasing its capacity by the addition of another burner; but where an opening is made in the manner here shown a removable pipe, X, can be inserted and removed at will, thus increasing the capacity of the stove by the addition of another burner. Of course the number of openings made and the number of additional pipes X that are used can be increased indcti nitely.

Having thus described my invention, I claiml. The combination, with the stand-pipe, of the casting I3', secured to its t-op and having the depressed top or portion I and the postor standard D cast therewith, the cap J, secured upon the post, and the ring K, which is secured upon the top of the casting by the cap, the casting having the two chambers I3 II formed therein, substantially as described.

2. The combination, with thestaud-pipe, of the casting B', secured upon its top and having the depressed portion or top I, so as to separate the vaporizing and commingling chambers, and the inclosing-walls M, formed as a part thereof, and the ring and cap J, suitable openings, L, being made through the top ot" the casting outside of the ring, so as to conduct vaporizingftlames inside ot the walls M, substantially as set forth.

3. The casting B', provided with a recess in its top, so as to receive the lower edge of the ring, and provided with the horizontal projections extending inwardly from its inner edge to center the ring, and having openings L through its sides for the escape of the vaporizing-tlames, in combination with the ring and cap, substantially as specified.

4. In a vapor-burner, the combination ofthe casting B', having the commingliug-chamber formed in its top, 'with the plate Q, placed over the top of the chamber and having an opening in one side, with the ring K and cap placed above the plate, substantially as shown.

5. The combination of the casting B', having a recess in its top to receive the ring, and a horizontal flange, Z, extending around the upper edge of the recess outside of the ring, with the ring and cap, substantially as set forth.

6. The combination of the casting B', having a recess in its top to receive the lower edge ot the ring, a horizontal flange, I Z, ex tending around the upper edge ot' the recess outside or" the ring, and openings L through theeasting for the escape of vaporizing-Ilames, with the ring and cap, substantially as specified.

In testimony whereofI affix my signature in presence of two witnesses.
